I too have been having this problem. But mine does not happen all the time. I would have to say, on the average, I have this problem about once a month. And on any day I have it, it may happen 2 or 3 times during the day. I have 3 email accounts: one through peoplepc and 2 through my current ISP, through 2 different servers. I send and receive through all 3 accounts, though peoplepc is not used as much as the other 2. So, on the average, for 29 days out of the month there is no problem whatsoever. Then all of a sudden, usually for about 10-15 minutes, I cannot send through the 2nd account through my current ISP. The error goes like this:
Sending message (date, time, etc)
Logging into smtpout.secureserver.net server....
Socket error # 0
While this is happening, if there are emails on that server, they will download to me just fine. If I am sending/receiving from the other 2 accounts they are just fine. Courier, which I came to Poco from, also did this, but probably less frequently than Poco.
I have even and gone and logged into the faulting servers webmail portal, with no problem. Once logged in, tried to send to no avail. Just glad it doesn't last that long.
Course, ISP, automatically says it is fault of my email program. Why then has it done it with 2 completely different programs? Strange!
I run Vista, Firefox 3.5.3, Comodo Security Suite, Spyware Terminator, Threatfire, and WinPatrol. Oh, yes, and MailWasher Pro.
My internet connection is a hybrid - radio/wireless from their tower to my radio/antenna to ethernet to computer. I live in the country and dialup out here was terrible - barely state legal. This is a bit more expensive than what in town broadband would be, but it beats the heck of my old dialup.
Anyway, I have this in through email help. Just thought I would post it here and see if anyone had any thoughts.
Thanks in advance

This could be well one of the causes.
You're running three HIPS applications, namely Defense+, Spyware Terminator, ThreatFire and on top of that WinPatrol. If that doesn't cause conflicts then I really don't know.

One thing to do would be to eliminate some of those applications.
In short I would keep CIS & WinPatrol. If you want an anti-spyware, go for SUPERAntispyware or MalwareBytes 'Anti-Malware. Only one realtime, the other one on demand.

As for Spyware Terminator make sure you didn't install ClamAv, since it could cause conflicts with CIS.

Well, I don't believe it happens often enough to shut down any of my apps. And it doesn't last long enough to try and turn them off as there are a couple that take stopping services - Threatfire takes turning it of and restarting. I could very easily go 2-3 months without it happening. I was just using the once a month as a "probable" average. If this were happening all the time, I would tend to agree with you, and that would give me the opportunity to take one out at a time, but I never know when its going to happen. And when it only stays that way for 5-15 minutes, that doesn't give you an opportunity to do much testing.
Sometimes when it happens I can hit send 3 times in succession and it will go through. Sometimes I may have to wait for about 10 minutes before it will go. I would think if it were one of the apps it would happen quite more often than that.
I already knew not to install the ClamAV. And I waited until Threatfire took care of their interaction with some AV programs before I installed it. I also use A-Squared Free, but only to scan every couple of weeks or so.
I've been using the internet since 1992 and have only had one bad infection. That was on this laptop the day I bought it. I brought it home, went online to specifically get the Windows updates and before I could finish downloading them I got that "RPC" infection that made you continually reboot. Wound up downloading everything I needed through my desktop, copied to a CD, and "fixed" this laptop.
So, unless it starts happening quite a bit more regularly I will probably stick with my apps. Though I am thinking about disabling the Comodo AV and installing Avira Free.

Last night I started having this problem. I have 2 email addresses through my ISP, through 2 separate mail servers. The "original" goes through the server provided by the ISP - it is not a real secure server and this showed up about 6-8 months ago when it was attacked and took down the whole "system". We were without access of any kind for a couple of days. During this time they made arrangements through GoDaddy and offered "new" email addresses to everyone that wanted them, going through GoDaddy.
So, last night after trying to send my message several times using my "new" address - this is the one that gives the problem all the time, GoDaddy - I switched my sending address back to my "original" address and the message went immediately. After it went, I went and changed the sending address back to the GoDaddy address and it still wouldn't go.
Doesn't that say there is something going on at the GoDaddy server rather than anything on my computer? And I wouldn't think it would have anything to do with my settings since it happens so infrequently????? What say you?

It sure does. Like I said, that error could be anything. There's no definite cause, so it means to find the culprit.In your case it's the server.

Not with your settings. However it's not advised to run more then one HIPS.

Disabling your AV isn't enough.
If you want to install another, uninstall CIS and install a firewall and Avira. There are still drivers loaded on startup which could conflict with Avira.
The same advice applies to running two software firewalls.
It's one or the other, not both.

I don't want to offend you with my advice. I've seen too many conflicts already on other computers to know what I'm talking about.

I also test security applications, but always in a snapshot.
On top of that images are taken regularly to be sure I don't mess up my system.

In short, your security setup is really an overkill.
There are other ways to secure your computer and it doesn't need to be taking a lot of resources.

That's my advice I can give to you, so it's up to you to take it or leave it.

And I still say my little test last night shows it isn't my problem. Why would I be able to send through the other ISP email address AND my peoplepc address, but not the one giving the problem.
And I also know that you don't run 2 firewalls. And, I think I can get the startup files taken care of with Autoruns.
We travel in our RV quite a bit and use "wireless" connections quite often. The only trouble I have ever had has been with the one address that won't let me send every once in while. The other 2 have never given a problem with not letting me send.

That's something for your ISP to examine.I can't help you with that.

And I also know that you don't run 2 firewalls. And, I think I can get the startup files taken care of with Autoruns.

Use it at your own risk, but make sure to take precautions.I only can warn you about possible consequences when running two antivirus programs. Like I said, disabling it won't be enough.

Since the other two don't give problems, but only one address does, it would mean there's something wrong with the connection to your ISP.
